is simple and inexpensive in construction,

highly efficient in operation, and well adapted to withstand the usage to which cotton choppers are ordinarily subjected. Other objects and advantages-of the invention will be fully understood from the following description and claims when the same are read in connection with the drawings accompanying and forming a part'of this specification, inwhich:

Figure 1 is atop plan View of a cotton chopper constructed in accordance with my invention. Fig. 2 is a side elevation of the same. Fig. 3 is a transverse section of the chop- .er. p Figs. 4, 5, 6, 7 and 8 are views illustrative of details hereinafter specifically referred to. Similar numerals of reference designate corresponding parts in all of the views of the drawings.

In the present and preferred embodiment Y of my invention the ground wheels 1 are carried by axle sections 2 and 3. The section 2 is solid, and the section 3 is tubular so as to telescopically receive the section 2.

The said sections are adjustably connected together as indicated by 4 in Fig. 4 so that the ground wheels '1' may be positioned at the frame comprises a forward transverse A tongue 8 isfiXed to the upper portions of the framemembers 5 and 6 and is ,extended forwardly from the latterfor the connection of draft animals.

Fixe'dtothe axle sectionsil and 3 isagear 9, and journaled at its opposite endsin bearings on the sleeve 7 andlthe forward frame member is a longitudin'al shaft 10. The sa d shaft 10 is provided with agearlll that is lntermeshed with the gear-9. The

v ed. revoluble choppers 16.; On, the shafts of the choppers 16 are sprocket gears 17 and 18 which are connected through the medium of sprocket-belts 19 and 20 with the spur gears 13 and 14, respectively. From this it follows that the rotation of the longitudinal shaft 10 as before described will be attended by rotation of the choppers about their axes. It also follows from the adjustable connection of the arms 15 to the longitudinal shaft 10 that the revoluble cotton chop Specification of Letters Patent. Patented Aug. 9, 1921 groundvwheels 1 are providedwith periphpers 16 may be positioned at various distances apart according to the widthof the space between the rows to be operated on.

Adjustably mounted on the side bars of the chopper frame are levers 21 through the medium of which the driver on the seat'22 is enabled to raise either of the choppers when occasion demands. The forward and lower arms of the said levers are connected through the medium of pendent bails 23 with the outer portions of the arms 15.

In the practical operation of my novel cotton chopper as thus far described it will be understood that incident to the traverse of a field by the chopper the revoluble choppers 16 will be rotated transversely and consequently will efficiently serve of purpose as cribed to them.

The adjustable connection of the arms 15 to the shaft 10 will be better understood by comparison of Figs. 2, 5 and 6 when it is stated that the arms 15 are longitudinally slotted as indicated by 15 to receive adjustable sleeves 16 one to each arm 15, and

which adjust-able sleeves 16 are adjustably fixed to their respective arms through the medium of nuts 17". The sleeves 16 serve to receive the shaft 10. V

In Fig. 7 I illustrate a construction in which the choppers 16 are hinged at 17* ratchet 50 is fixed on the axle section,'and

the wheel is loosely mounted on said section and is provided with a spring pressed pawl 5 1 in'engagement with the said ratchet. This provision manifestly enables the axle to turn while the inner ground wheelis at rest as when the machine is being turned.

As shown in Fig. 2 the gear 11 is splined and shiftable longitudinally on the shaft 10; the said gear being provided with a circumferentially grooved portion 50 engaged with a lever 51 having a detent for cooperation with a fixed segmental rack 51. This provision is made in order to enable .the

driver to start and stop the chopping means at will. 7 u Having described my invention, .What I claim and desire to secure by Letters-Patent, is u 1. A cotton a sectional axle connected with the frame and having means to adjustably connect its seetions together whereby ground wheels on the axle section may be spaced at different distances apart, agear fixed to said axle sectiorga longitudinal central shaft carried by the frame, a gear on the shaft and interine'shed with the first-named gear, sprocket gears fixed on the longitudinal shaft, slotted 7 arms receiving the longitudinal shaft in their slots, sleeves adjustably receiving the longlt-udlnal shaft, nuts on sand sleeves to adjustably fix thesame to the arms, cotton choppers mounted in theouter portions of the arms and having shafts and sprocket gears thereon, and sp' rocket belts connecting the sprocket gears on the shaft and the sprocket gears of thecottonrc'hoppers.

2. The combination in a cotton chopper of a longitudinal shaft, means carrying said shaft,means' to rotate the shaft, cotton choppers arranged at opposite sides of the vertik cal plane of said shaft and-having shafts in parallelism to the first-named shaft, and driving connections between the first-named shalt'and the secondsnamedshafts. v p

In testimony whereof I affix my signature.
